IMPRESSING MACHINE.

Application tiled. February 21, 1913. Seria] No. 218,450.

To (zZ/Z whom t may concern:

Be it known that I, MARTIN O. Rnrinuss,

Philadelphia,

ing is a specification. One obj ect of my relatively simple,

Pennsylvania,

have invented of which the Jfollowinvention is to provide a substantialand conveniently operated machine for printing or making an impressionupon a sales slip or similar paper the device being particularly adaptedto allow of the easy insertion and removal Aoit the plate upon which iscarried the type, lettering, etc., from which an impression is to bemade.

A further object is to provide a machine of the above noted character inwhich the parts shall be so arranged and constructed that it shall Ibeconveniently portable and shall be especially designed to receiveaddress vplates each projecting or formed eral plane.

It -is also desired to having side or edge flanges atan angle yto itsgenprovide a novel detail construction for the plate-carrying head andplunger with their associated parts, as well as Va novel and relativelysimple device for automatically feeding the inlring ribbon un,-

der and in engagement with the plate from which an impression is 'to' bemade.

The invention also vision of a device `for contemplates thepropreventing the deposit of ink or coloring material Jfrom the inkribbon upon the address plate,

which device includes a pair of spindles adjustably supporting a paperor other strip between said plate and ribbon.

These objects and other advantageous ends l secure as hei-ei natter set`forth, reference being had to the accompanying drawings, in. which 4ig.1, is a sidc elevation ol an impressing device constructed according tomy rvinvention,

Fig. 2, is a front chine shown in Fig". 1

Fig. 3, is a side elevation partly elevation of the main verti- Fig. 5,is a horizontal section on the line 5-5., 2, and

Fig. 6, is an inver carrying head.

ted plan of the plate- In the above drawings, ll represents a suitablesupporting base having at its rear an upwardly and forwardly projectingstandard which is vertically elongated under the front of said base ytoprovide a guideway for a plunger 3. The top of this front portion of thestandard is forked for the reception of an operating lever /l and thisis journaled on a spindle 5 extending between the branches of said fork.The upper end of the plunger is ,provided with a lrearwardly extendingarm A6 whose upper face is designed to be-engaged by a cam-likevextension 7 from the rear of the lower end of the handle, while itsunder face is at all timles engaged by a coil spring 8 vmountedin avertically extending recess of the standard 2. The lowerend of theplunger 3 has fixed 'to it by a pin 11 ahead 9 elongated from front torear and whose under face has two parallel undercut grooves 10 extendingalso from trent to rear, for the reception of the turned over fianges -lof an address plate rllhis latter Lpreferably consists of an elongatedpiece of relatively stiii? sheet `metal having pressed out from itletters or symbols constituting, in the present case, a business addressor residence, and it is 'free to slide longitudinally of the head 9 inorder to pei'- mit of its convenient insertion and removal. The upperface of said plate is designed .to be immediately adjacent or in closecontact with that portion ,ofthe under face of `the head 9 between thegrooves-10.

The rear end of the head 9 is formed with two oppositely projecting lugs12 to which is fixed a vtransversely extending bar 13 preferably bymeans of screws). The ends of this bar are turned up and. as shown inFig. 5 have respectively iixed to them a pair of forwardly extendingstationary spindles 11i whose front ends are threaded for the receptionof thumb nuts 15. On each of Athese spindles is rotatably mounted a tubeor sleeve 16y to whose rear end is ixed a ratchet wheel 17 ;-it beingnoted that each oit' said sleeves is longitudinally slotted in orderthat it may increase slightly in diameter when the thumb nut 15 isscrewed upon its spindle so as to exert sufficient pressure upon itsadjacent end. The Vnut and washer also serve to removably retain on thesleeve a reel 19 holding a portion oi the inking ribbon 2O which, asshown Fig. 2, is designed to extend from one of the reels across theunder face of the head 9, over the plate iv and then to the second reel.

Respectively below the spindles 14 the bar 18 carries two other spindles18 on which is wound a paper strip or web of fabric 18" extending fromyone of these auxiliary spindles, transversely across and in contact withthe under surface of the address plate, to the second auxiliary spindle.Said paper strip is thus interposed between said plate and the uppersurface of the ink ribbon 2O and, as its spindles are rotatable, it maybe drawn across the head from time to time so that there will at alltimes be a clean surface adjacent the raised dress plate.

F or causing` the inlring ribbon 20 to be fed across the head 9, I mounta longitudinally slidable bar 21 in a suitably formed transverselyextending recess in the standard 2, preferably to the rear of the recessfor the spring 8, andto the ends of this bar I pivot two oppositely hungpawls 23l which, under the action of gravity, may rest upon the ktoothededge ofthevratchet wheelsl? respectively; Said bar 21 is of such lengththat when either of its pawls is in engagement with the side of thestandard, the pawl on its opposite end engages the .teeth of theadjacent ratchet wheel. i In order that the bar 21 with its pawls shallremain in a given position, I mount a set screw 24 in the standard insuch position that it may be turned into holding engagement with saidbar at will.

Tith the yabove described arrangement of parts, any desired one of anumber of address plates is inserted in the grooves 10 of the head 9,and the sales slip, bill or other paper upon which it is desired toprint or impress the address on said plateiis p laced under the headupon the flat upper face of the front portion of the base. If now thelever or handle 4 is swung back and down, its cam projection 7 engagesthe arm 6 of the plunger 3, forcing this latter down in i tsguidewayagainst the action of the spring 8 and ultimately causing theprojecting raised portions of the address plate to print upon the salesslipthe ink ribbon20 and the paper strip 18"' being of courseinterposed. Thereafter, as the lever /1- is released, the spring 8 actsto raise the plunger 3 to its normal-elevated position and just before`the head 9 reaches its upper position, one

of the pawls 23 strikes the teethv of its ratchet 17, forcing this withthe attached tube 16 and the reel 19 to turn through a part of onerevolution. As a result a short I length of the ribbon 20 is wound uponthis reel and a corresponding length is drawn from the other reelwhosemovement is retarded to some extent by the friction exerted upon it byits tube 16, whose central portion portion of the ad-` has been slightlyexpanded for this purpose by setting up its -thumb nutl. A fresh portionof the ink ribbon is thus brought under the printing face of the addressplate after each depression of the head 9, and thel consequent windingof said ribbon upon one of the reels is continued until it ispractically `filled. The operator then loosens the set screw 24; andmoves the bar 21 longitudinally in its recess until the second pawl 23is brought into a position in which it will be engaged by its adjacentratchet wheel. Since the teeth of the latter are disposed oppositely tothose of the first ratchet wheel, the subsequent operation of the devicewill reverse the direction of the movement of the ribbon, causing it tobe woundup on the second. reel.

Itis particularly to be noted that the address plate may be inserted orremoved with the greatest ease and a succession of impressions made fromany of a number of different plates without loss of time. means of thepaper or fabric strip between the plate and the ink ribbon, the formerisy kept clean and as said strip becomesworn or filled-'withl ink at anyone point, it may be replaced by a fresh portion adjacent the addressplate by turning one of the auxiliary spindles 18 to wind up a suitablelength thereof. In order to insure that the ink ribbon and paperstripshall be substantially flat over the face of the address plate, Iprovide two parallel guide bars 22 respectively on opposite sides of thehead 9. Said bars are shown as flat `elongated plates spaced away fromthesides of said head and mounted with their lower edges slightly abovea horizontal plane including the raised portions of the address plate.With this arrangement the ink ribbon and paper strip on one side of themachine pass from their spindles over the lower edge of one of the guidebars 22, thence across the face of the address plate, over the secondguide bar and to their spindles on the opposite side of the machine.

Obviously the inking mechanism, consisting of the bars 13 and 21 withtheir attached parts, may be omitted without departing from myinvention, in which case the docul ment operated on would be impressedby the address plate instead of printed.

I claim: i

l. The combination in an impressing ma! which an impression is to bemade; a trans versely extending bar mounted on said head; two pairs ofspindles mounted on the bar respectively on opposite sides of the head;a protective strip passing from a spindle on one side ofthe head, acrosssaid impressing` member to a second spindle on the opposite side of thehead; and an ink ribbon extending between the two remaining spindlesover said protective strip; with means for actuating the head to make animpression.

In witness whereof I aix my signature.

MARTIN O. REHFUSS.
